This equation is just a simple Pythagorean theorem ( if you were not aware, it’s a2 + b2 = c2. To get c is to find the square root of c)

The correct answer is D. Hope i could help
Answer:
A
Step-by-step explanation:
Okay cool, so basically the formula is a^2 + 2a square root a square over 4 + h square.
We have to us e the Pythagorus theorem to find the height.
3^2 + h^2 = 36
9 + h^2 = 36
h^2 = 27
h ~ 5
Let's plug in the values from the formula.
The closet answer should be A
